Philips Streamium MCi8080/12 User Manual page 77

The header files "include/image.h" and "include/asm-*/u-boot.h"
define interfaces to U-Boot. Including these (unmodified) header
files in another file is considered normal use of U-Boot, and does
*not* fall under the heading of "derived work".
Also note that the GPL below is copyrighted by the Free Software
Foundation, but the instance of code that it refers to (the U-Boot
source code) is copyrighted by me and others who actually wrote it.
